An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A computing system for determining osteogenic loading from an exercise apparatus for performing an exercise is provided. The exercise apparatus includes a loading interface, a frame, a linear adjustment system interposing between and fixedly coupled to the loading interface and the frame, and a sensor coupled to the linear adjustment system. A position of the loading interface of the exercise apparatus is adjusted through a movement of the linear adjustment system at one or more intermediate positions of a plurality of functional positions of the loading interface. A force exerted by a subject on the loading interface at the position in the one or more intermediate positions is received. A measurement of the force exerted by the subject on the loading interface at the position in the one or more intermediate positions from the sensor is obtained. A corresponding osteogenic loading for the force exerted by the subject is determined.

A device for an exercise apparatus includes a linear adjustment system and a sensor coupled to the linear adjustment system. The exercise apparatus includes a loading interface and a frame coupled to the loading interface for performing an exercise. The linear adjustment system fixes the loading interface of the exercise apparatus at any one of a plurality of functional positions in a functional range of the loading interface. The sensor measures the force exerted on the linear adjustment system. A correlating mechanism is used to correlate the force exerted on the linear adjustment system with the force exerted on the loading interface. The device allows exercisers to exert high or maximum loads in any one of a plurality of positions throughout their entire range of motion without first passing through a weak range of motion.

An exercise device for alternating movement of arms and legs by which users perform alternating active exercises and passive exercises repetitively is revealed. The exercise device includes a base, a hand driving member, and a leg driving member. Both the hand and leg driving member are pivotally connected to the base while the leg driving member is arranged under the hand driving member. One end of the hand driving member and one end of the leg driving member are configured to be pivotally rotated on the base. The hand and leg driving members are pivotally connected by a linkage. By the pivotal connections of the above parts, the hand and leg driving members are linked and moved with each other so as to lift up or press down arms and legs for stretching. The stretching of arms and legs also generates pressure on the abdomen of the user to exercise his or her abdomen.

A reciprocating transmission structure of an exercise machine, mounted to a frame of the exercise machine, includes a first reciprocating member, a second reciprocating member, a main rotating wheel, a first link, a second link, and a resistance wheel. The first reciprocating member reciprocally moves with a first reciprocating pivot portion as its axis. The second reciprocating member reciprocally moves with a second reciprocating pivot portion as its axis. The first link and the second link drive the main rotating wheel to rotate with a rotating shaft as its axis. The main rotating wheel drives the resistance wheel to rotate. After the first reciprocating member and the second reciprocating member move reciprocally, the resistance wheel can be driven to rotate by the cooperation of various components. The exercise machine is suitable for performing exercises related to reciprocating movement, and the operation is easier.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A sports training device includes a stand, pivot axis, elements for a person training to apply force, and load device for creating an adjustable load. The load device includes weights and a U-shaped guide acting to protect against unauthorized removal of the weights, one end of which guide is connected via a bracket to the pivot axis, which is secured to the stand. The pivot plane of the load device is directed perpendicular or parallel or at an angle to a support surface. The center of mass of the load device is shifted, in the presence of even a minimal load, left or right from the pivot axis or coincides with the pivot axis. The elements for a person training to apply force are installed, relative to the load device, at a given height from the support surface in accordance with the direction of force from the person training and in accordance with the group of muscles receiving the load.

A locking device for an exercise system may include a locking member having a contact portion and configured to move between a first position and a second position. When in the first position, the contact portion of the locking member is not in mechanical communication with the resistance mechanism of the exercise system, thereby allowing movement of the at least one moveable assembly. When in the second position, the contact portion of the locking member is in mechanical communication with the resistance mechanism of the exercise system, thereby preventing movement of the at least one moveable assembly.

A ground-effect footplate against which a user applies plantar force and moves their foot in 3D across all seven lower-extremity biomechanical axes to accomplish specific as well as global ambulatory objectives related to lower extremity performance improvement, injury prevention and rehabilitation. A device comprising at least one articulating leg connected to a ground-effect footplate and a surface for a user to position against. The device can be used in conjunction with software to create virtual ambulatory environments that mimic GRFVs and cause moments of force that initiate muscular activations that substantially mimic human ambulation, and can couple those movements with non-functional movements in order to improve ROM, speed, strength, and proprioception.
